Sickle cell disease occurs as a result of a single point mutation of βGlu6 in normal hemoglobin (Hb A) to βVal6 in sickle hemoglobin (Hb S) (Pauling & Itano, 1949; Ingram, 1959).When Hb S is in its deoxygenated T-state form, it assembles into long, rigid, insoluble fibers that lead to sickling of red blood cells (RBCs) and several cascading …
